ALFRED M. DEMU TI-I, OF CHICAGO, ILLINOIS, ASSIGNOB TO U. S. SLIOINGMACHINE COMPANY, OF LAPORTE, INDIANA, A CORPORATION OF INDIANA,

WORK HOLDER FOR SLIGING-MACHINES.

Application filed November 10, 1917.

1 b all whom it may concern Be it known that l. ALFRED M. DEMUTH, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and use fulImprovements in VVorkdiolders for Slic ing-Machincs, of which thefollowing is a specification.

This invention relates to improvements in work holders for slicingmachines. In slicing machines of the type embodying a rotary cutter anda reciprocating carriage, it is customary to provide a feeding platemounted upon a carriage so as to intermit tently advance the articletothc cutter during the reciprocation of the carriage. In order to holdthe article with relation to the feeding plate, spaced uprights areprovided which are connected with the plate, and a clampin bar movesupon the uprights and cooperates with the feeding plate.

lVith this form of article holding means, and as generally constructed,it is impossible to hold the article so that it will be entirely out upor sliced, as it is necessary to leave a considerable port-ion of theend of the article which cannot be sliced, owing to the fact that the.clamping means must extend for a considerable distance over the end ofthe article to grip the same, and with the holding members which areprovided with laterally projecting pins. the ends of the pins protrudeinto the meat and into the path of movement of the cutter before the endof the article is reached.

It is one of the objects of the present invention to pr vide an improvedwork holder which ill not only secure and hold the article by the verytip end while being cut so that the entire article may be cut up, butone which will also serve as an individual holder adapted to be readilyapplied to any machine and as readily removed therefrom, and whichholder embodies an article support and. a cooperating clamping member.

A further object is to provide an improved article support adapted torest upon the feedin plate so as to engage and be held in position bythe uprights carried by the feeding plate, and an improved clampingmember cotiperating with the support, said clamping member being alsoheld in position and being movable upon the same uprights or guideswhich hold the article support, so that the article support may he readSpecification of Letters Patent.

ily attached and detached from the machine adapting it for an individualarticle holder, rendering it unnecessary to remove the article from theholder after being once placed thereon.

To the attainment of these ends and the accomplishment of other new anduseful objects will appear, the invention consists in the features ofnovelty in substantially the construction, combination and arrangementof the several parts hereinafter more fully described and claimed andshown in the ac companying drawings illustrating this invention and inwhich;

Referring more particularly to the drawings, the numeral 10 designates afeeding plate usual in the type of slicing machine embodying a rotarycutter and a relatively reciprocating carriage, and which plate 10 ismounted upon the carriage to be intermittently fed or moved during thereciprocation of the carriage to advance the article to the cutter, asis usual in machines of this character.

Uprights 11 are carried by the plate 10 and are provided with teeth orshoulders 12 on the inner face thereof and extending lengthwise of theuprights.

This plate 10 is usi'ially inovided 'ith pins or projections 13extending above its upper face and upon which plate the article isadapted to be placed so that the pins will impale the article.

ith the present invention, the article is held in position upon theplate by means of a supplemental support let which may be of any desiredsize and configuration and may be constructed of any suitable material,the bottom of the support 14 is recessed or hollowed out as at 15 sothat when the support 14: is placed upon the plate 10, the pins 13 onthe plate willproject into the hollow portion 15 of the support and bymeans of which the support 14 is adapted to be placed upon any machine.

In the form of the invention shown in Figs. 1 to a, the support 14 isprovided with upright portions 16 extending along the lateral edgesthereof and the extremities of these upright portions 16 are deflectedlaterally as at 17 and if desired, the edges of the portions 17 may becurved as at 18 to form a suitable and convenient handle for grippingthe support 14C to transport the same.

The portions 17 are provided with apertures therethrough and surroundingeach of the apertures is an upwardly projecting boss or collar 19. Theaperture and boss are located in such a position that the uprights 11will pass therethrough when the support 1% is placed in position, andthe front edge 20 of the support is arranged to stand flush with thefront edge of the plate 10, as shown more clearly in Fig. 3.

The support 14 is provided on its under face with enlarged or projectingportions 21 having apertures extending therethrough in a directiontransverse to the front edge of the support and pins 22 are provided andadapted to be secured to the support 14. These pins 22 may be of anydesired size and length and the rear portions 23 thereof are preferablyarranged at an angle to the pointed extremities of the pins, and areadapted to be driven into the openings in the portions 21. The front ofthe support is provided with a suitable recess communicatin with each ofthe apertures in the portions 21, so that when the portion 23 of the pinis seated in the aperture, the body of the pin will be seated in therecess so that the outer face of the pin will stand substantially flushwith the outer edge 20 of the support 14:.

With this improved construction, it will be manifest that in the eventthat any one or more of the pins become broken or damaged, they can bereadily removed by turning over the support 1 1 and striking theprojecting extremity of the portion 23 of the pin, thereby driving thepin out of its seat without dismantling any of the other portion of themechanism. A new pin may be readily inserted as will be understood- Thesupport 14 may also be provided adj acent its rear end with upstandingpins 24 which cooperate with the pins 22 and impale the article toassist in holding the article in position.

A clamping member is adapted to cooperate with the support 14 and may beof any desired configuration, preferably comprising a body portion 25 ofany suitable material, having apertures through its extremities throughwhich the uprights 11 are adapted to pass. This clamping member may beprovided with a face plate 26 constructed of any suitable material andwhich plate is provided with teeth 27 extending thereacross, and theteeth are preferably arranged so as to extend in a direction toward oneend of the clamping member and in a direction in opposition to theaction of the cutter upon the article so that when the article is beingcut, any tendency of the cutter to move the article laterally, will beresisted by the teeth 27 of the clamping member and which teeth will beforced into the article by such action of the cutter. This plate 26 maybe secured to the body portion of the clamp 25 in any suitable mannersuch as by means of fastening bolts or devices 28, so that the plate maybe readily removed when desired.

The clamping member is provided with a series of depending pins orprongs 29, the rear portion of each of which is dcfiected laterally andis adapted to be seated in a suitable opening in the member 25 so thatthe outer face of the teeth, when the latter are seated, will standsubstantially flush with the front edge of the clamp and also with thefront edge of the pins 22, support 14 and plate 10. The pins 29 are ofsuch a length as to impale the extreme end of the article, so that theentire article may be sliced up, permitting the cutter to operate inclose proximity to the outer face of the pins. In order to permit ofready removal of the pins 29, the portion 25 of the clamp is providedwith a longitudinal re cess or groove 31, into which the extremity ofthe portion 30 of the pins 29 projects, and the plate 26 is providedwith a rib 32 adapted to project into this groove or recess whichassists in holding the plate.

Thus it will be seen that when it is desired to remove any one or moreof the pins 29, this may be readily accomplished by detaching the plate26 which will permit access to be had to the extremity of the portion 30of the pin 29, to drive the same out of the recess in which it isseated. The edge of the plate 26 is also adapted to stand flush with theouter face of the pins 29 and obviously the edge of the plate adjacentthe pins may be provided with recesses to receive the pin.

A handle 83 is secured to the clamping member intermediate its ends andby means of which the clamp may be raised or lowered. In order to arrestthe downward movement of the clamping member so as to protect the endsof the pins 29, and also additional pins Set which may be provided inthe clamping member, the clamping mem her is provided with a recess 35adjacent each of the uprights 11 and each recess is adapted to receivethe respective bosses or collars 19, the recess being of such a sizethat when the boss or collar engages the bottom of the recess, theextremities of the pins 29 will be. prevented from striking the sup-port14:.

In order to hold the clamp in its adjustedposition, suitable lockingmeans is provided and the clamp is adapted to be looked upon theuprights or guides 11 of different machines, no matter whether the teeth12 are arranged on the inside or the outside of the guides.

The locking means preferably comprises two members 36, 37, the extremityof each of which is provided with an opening 38 of a size to permit theupright 11 to pass freely therethrough and these members 36, 37 areadapted to move in a suitable guideway formed by members 39, 4:0,removably secured to. the member 25 of the clamp and the fastening bolts40 by means of which the handle 33 is secured in position, are ad ptedto pass through suitable elongated slots 11 in the members 36, 37 whichserve as an additional means for guiding them.

The walls of the openings 38 adjacent the inner and outer faces of theuprights are deflected or inclined as at 42, d3 to form an edge which isadapted to pass under the teeth 12 so that when the teeth are on theinner side of the upright, as shown in Figs. land 2, and the members 36,37 are moved into the position shown in Fig. 2, the faces 43 thereofwill pass under the shoulders 12 and lock the clamp in position. mienthe teeth are on the outer face of the uprights or guides 11 as in Fig.6, the members 36, 37 will be moved in the opposite direction until thefaces 42 of the openings 38 will pass under the shoulders 12 as shownmore clearly in Fig. 6. In order to accomplish this movementof themembers 36, 37, an operating handle 1 i is provided which is pivotallysup ported as at 5 .5, the extremity of th member 37 being pivotallyconnected as at 46 with the handle, and the extremity of the member 36being pivot-ally connected as at il with the handle. In order to permitof a free movement of the members 36, 37 to accomplish the lockingoperation above de scribed, the end of the member 36 is preferablycurved as shown so as to permit it to pass over the pivot 45.

lVhen it is desired to place the clamp in position or remove it from theuprights or guides, the handle ii is shifted to what. is termed aneutral position, at which time the clamp is adapted for free movementupon the uprights.

\Vith this improved construction, it will be manifest that no matterwhat type of machine the clamp is applied to, that is whether the teethare on the inside or outside of the upright, the clamp will be securedin position by shifting the handle 4st to one side or th other of theneutral position.

In the form of the invention shown in Figs. 7 to 10, the support 49provided with laterally deflected portions 50 which extend in a planeabove the horizontal plane of the body portion of the support and ispro- 'ided with additional pins 51 which are flush with the front edgeof the support as are also the pins and the pins 51 are adapted toengage any article which is of a size to project over the laterallydeflected portion 50 of the support.

This support 49 is provided with suitable handles by means of which thesupport may be transported and with both forms of the invention, it willbe manifest that if the article is once placed upon the support, it maybe allowed to remain thereon as an individual holder so that the articleneed not be removed from the support after once being placed inposition, and may be readily placed in the icebox on the support.

.lVith the form of the invention shown in Figs. 7 to 9 and in order thatthe pins 51 will not interfere with the operation of the clampingmember, the clamping member is provided with a recess 54 adjacent eachof the pins 51 to receive the latter when the clamp is moved inproximity thereto as shown more clearly in Fig. 10.

With this improved construction it will be seen that the support andclamping member are not only adapted to be held in position' and operateupon the same guides or uprights, which are already on slicingmachinesof this character, but the position of the teeth. 12 on the uprights isimmaterial as the securing member on the clamp is adapted foruseoneither type of machine.
